FINE PRINT: The 888 will not
remove any mechanically attached materials, glues. epoxies or trapped objects.

The 888 IC Yield Master
consists of three components:

1. Cleaning Head for
ionizer blow off and vacuum suck back
2. Ionizer Unit
3. Vacuum Box with HEPA Filter

1. The Cleaning Head

Special cleaning head configurations are available for
different strip, package or wafer sizes.

Cleaning Head:
Each Cleaning Head is built to match the product which will be passed
under it for cleaning. The head incorporates ports for particle blow off and
vacuum suck back.

2. The Ionizer Unit

Just blowing the particles off the devices is not enough !

Most foreign materials are held onto a package because of static. The 888
employs a flow of delicate ionized air to discharge the package and free the
particles from the device. At the same time 888 is blowing down with ionized
air or nitrogen blanket, a vacuum port is sucking the particles into a
filtered box. Just ionizing the air around a device to be cleaned will not
remove harmful particles, airflow must be part of the process. Vacuuming
while performing ionized blow off will assure that no particles will be
present on the device at the process step.

The
Ionizer

When fed from an ultra-clean gas source, the ionizer of the 888 operates 10
times better then Class 1 clean room requirements. To virtually eliminate
particle emissions, the design includes a tightly controlled emitter point
shape, corona voltage and current. Careful material selection and control of
internal geometry ensure ultra-clean ionized gas delivery. The ionizer uses
a patented, intrinsically balanced technology, which ensures electrical
neutrality and safe operation in the tight confines of the production
equipment. It is based on extreme electrical isolation and relies on
conservation of charge to achieve balance. With this technology, the 888's
ionizer will never need calibration.

Ionizer Features:

Ionizes either clean dry air or nitrogen

Precise delivery of balanced ionization to confined areas

Class 1 operation

No calibration needed

Maintenance-free for two years

3. Vacuum Box with HEPA
Filter

DO THE MATH:
You are running 1,000,000 devices per week. Your yield is 97% +-. You are
throwing away 30,000 units per week or worst yet some are sent your customers.
Out of the 30,000 half are rejected because of foreign particles, The 888 can
save 50% of this 15,000. That's 7,500 units per week that could be saved by the
888. 390,000 per year! Can you afford not to try the 888?

The Vacuum Unit:

The vacuum unit of the 888 is self-contained system, which incorporates a
highly reliable, maintenance-free vacuum pump. The harmful particles are
drawn into the pump box and into a 0.3 Micron HEPA filter before returning
the air to the room.

Vacuum Unit Features:

Self-contained

Maintenance-free

Oil-less Operation

0.3 Micron HEPA filter

HEPA Filter:
Depending on the environment, it is recommended that the filter be changed
every 250-500 operation hours.

Removes These Harmful Particles and More:

Packing Foam

Paper Fibers

Machine Created Particles

Skin

Hair

Loose Bonding Wire

Dust ...

Note: The 888 will not remove particles that are mechanically
connected to the leadframe or die, nor will it remove any particles that
are trapped under the wires of a wire-bonded device.

Yield
Improvement:

The 888 can be retrofitted to a wide range of process equipment. The 888's
technology has been field proven to increase the final yields of integrated
circuits by removing harmful foreign materials from leadframe during the IC
manufacturing process. We are sure you, and your customers, will have peace
of mind knowing that every leadframe will be cleaned of foreign materials on
each machine where a 888 is used.
